ABSTRACT:
A magnetic storage device having a stack of spaced flexible magnetic disks and an access arm carrying a magnetic transducer moveable between adjacent disks in the stack for accessing the disk surfaces. The access arm is blunt on one side edge and is sharp on the other side edge and increases gradually in thickness from the sharp edge to a position of maximum arm thickness adjacent the blunt edge at which the magnetic transducer is embedded in the arm. The disks rotate so as to move across the arm from the sharp edge toward the blunt edge, and the disks thus closely follow the surfaces of the access arm and particularly the surface of the transducer.
